Chapter Introduction Title chapter 1 The DART-FIRE Small Screw System is a cannulated, partially-threaded titanium alloy screw system that is indicated for use in bone reconstruction, osteotomy, arthrodesis, joint fusion, fracture repair, and fracture fixation of bones appropriate for the size of the device. With self-drilling and self-tapping headed and headless compression screws Figures 1 & 2, in diameters ranging from 2.0mm to 4.0mm (Table 1), the DART-FIRE Small Screw System provides extensive versatility for surgical procedures of the foot, within one comprehensive system.

System Basics»» The DART-FIRE Small Screw System offers the simplicity of self-drilling and selftapping cannulated compression screws in diameters from 2.0mm to 4.0mm.»» All DART-FIRE Small Screws are manufactured from titanium alloy (Ti 6Al-4V) to provide consistent strength.»» Screws are color-coded by diameter and head type to easily identify associated instrumentation (Tables 2 & 3).»» Pilot Drills, Countersinks, and Drivers have corresponding color-coded banding to match screw diameter, simplifying the pairing of instrumentation with screw selection figure 3.»» While the screws are self-drilling, cannulated drill bits are included for use in hard cortical bone, when an oblique approach is desired, or when bicortical fixation is required.»» Cannulated Countersinks are provided to recess screw heads into the cortex of the bone.

chapter Chapter Intended 12 Title Use Intended Use The DART-FIRE Compression Screws are cannulated screws offered in various diameter and lengths. Screws are available both headed and headless, and all screws are manufactured from titanium alloy. Indications The DART-FIRE Compression Screws are indicated for use in bone reconstruction, osteotomy, arthrodesis, joint fusion, fracture repair, and fracture fixation of bones appropriate for the size of the device. Screws are intended for single use only. 6 Chapter 2 Intended Use
DART-FIRE Small Screw System Surgical Technique chapter 13 Preoperative Planning The DART-FIRE Small Screw System is composed of a variety of small diameter screws in headed and headless versions. The correct screw selection for the procedure is extremely important, and preoperative consideration of the proper screw size and design will increase the potential for surgical success. K-wire Placement The appropriate K-wire (Tables 2 & 3) is advanced across the fusion or osteotomy site. FIGURE 4 Verify the desired positioning of the wire fluoroscopically. FIGURE 4 Insertion of an appropriate sized K-Wire. Screw Diameter Selection Appropriate screw diameter is selected based on the procedure to be performed. Screw Length Determination Measure screw length by using the Cannulated Depth Gauge. FIGURE 5 Slide the tip of the Cannulated Depth Gauge over the K-wire and down to the surface of the bone, ensuring that the gauge is seated flush to the bone. The gauge measurement indicates the depth from the surface of the bone to the tip of the K-wire; adjust accordingly for countersinking or lagging. FIGURE 5 Measuring screw length with K-wire.

Drilling The DART-FIRE Small Screw System has been designed to be self-drilling and selftapping. However, in some situations such as hard cortical bone, bicortical fixation, or when an oblique approach is desired, drilling may be necessary. Additionally, it is recommended to pre-drill the near cortex when using headless screws to prevent the proximal threaded portion from splitting or cracking the cortical shell. FIGURE 6 Slide the appropriate color-banded drill bit (Table 2 & 3) over the K-wire. Under power, drill just past the osteotomy or fusion site. FIGURE 6 Drilling of the screw canal. Countersinking To ensure complete seating of the headed screws, the appropriate countersink (Table 5) may be used. Load the appropriate color-banded countersink onto the Cannulated AO Driver Handle, and turn the countersink in a clockwise motion to penetrate the cortex of the bone. FIGURE 7 FIGURE 7 Countersink drilling. 8 Chapter 2 DART-FIRE Small Screw System Surgical Technique
Verify Screw Length Prior to inserting the screw, verify the length and diameter of the selected screw with the screw gauge provided on the DART-FIRE Small Screw System screw caddy. Note the use of Angled Tip Forceps may facilitate screw removal from the caddy. FIGURE 8 FIGURE 8 Verification of screw length on caddy. Screw Placement Load the appropriate Driver (Tables 2 & 3) into the Cannulated AO Driver Handle. Place the screw over the K-wire and use the Driver to advance the screw into the bone, until the head is completely countersunk within the bone. FIGURE 9 Depending on the stability of the first screw, procedure type, and patient related factors (obesity, postoperative compliance issues), multiple screws may be used for additional fixation. In the case of soft bone, a washer may be used under the head (for headed screws only) to limit excursion of the screw into the bone. Slide the screw through the washer until it contacts the head and insert the screw over the K-wire as detailed above. Remove the K-wire and perform surgical closure.
